我正在尝试为我的控制器进行集成测试，但由于某种原因，测试上下文无法解析响应并导致测试失败，并抛出406个HTTP代码。
我在上下文中有jackson mapper bean。
以下是代码：
控制器：
@Controller @RequestMapping({"/user"}) public class UserController { Logger logger = LoggerFactory.getLogger(UserController.class); @RequestMapping(value = "isloggedin",method = RequestMethod.GET, produces = "application/json") @ResponseBody public ServerResponse<Boolean> isloggedin() { return new ServerResponse<Boolean>(true, HttpStatus.OK, "logged in"); }
测试环境：
@PropertySources(value = { @PropertySource("classpath:/application.properties")}) @ComponentScan(basePackages = {"X.Y.Z.controllers", "X.Y.Z.webresources"}) @ContextConfiguration(classes = {WebMvcConfig.class}) public class ControllerIntegrationUnitTestContext extends AbstractJUnit4SpringContextTests {}
在WebMvcConfig里面我有：
@Bean @Autowired public RequestMappingHandlerAdapter requestMappingHandlerAdapter(MappingJackson2HttpMessageConverter d){ RequestMappingHandlerAdapter requestMappingHandlerAdapter = new RequestMappingHandlerAdapter(); List<HttpMessageConverter<?>> messageConverters = new LinkedList<>(); messageConverters.add(d); requestMappingHandlerAdapter.setMessageConverters(messageConverters); return requestMappingHandlerAdapter; }
测试类：
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(classes = {ControllerIntegrationUnitTestContext.class}) @WebAppConfiguration public class SampleUnitTest { private MockMvc mockMvc; @Autowired private WebApplicationContext webAppContext; @Before public void setUp() { mockMvc = MockMvcBuilders.webAppContextSetup(webAppContext).build(); } @Test public void testrun() throws Exception{ mockMvc.perform(get("/user/isloggedin").accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk()).andExpect(content().string("true")); }}
以及运行测试时出现的错误：

我有点坚持这个，不知道还有什么可以做这项工作
进度：
RequestMappingHandlerAdapter不在上下文中，现在是。但我得到了一个
java.lang.IllegalStateException: Failed to load ApplicationContext ... Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.core.JsonProcessingException at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358)

更新了杰克逊版本，现在一切正常。
答案 0 :(得分：3)
你的处理程序用
映射@RequestMapping(value = "isloggedin",method = RequestMethod.GET, produces = "application/json")
生成 application/json。为此，您的客户必须Accept application/json。目前，您的MockMvc请求未指定此类Accept标头。添加一个。
